To all whom it may concern.-

Be it known that I, GEORGE L. WELLER, a citizen of the United States, residing at Elyria, in the county of Lorain and State of Ohio, have invented certain new and useful Improvements i'nWood-Fiber-Outting Machines and I do declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to wood-fiber-cutting machines; and one of the objects of the invention is to produce a simple and efficient machine which will out two logs at the same time, and thus practically double the capacityof the machine, all substantially as shown anddescribed, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a plan view of my new and improved ma chine, and Fig. 2 is a side elevation of the same. Fig. 3 is a side elevation on sectionline 00 m, Fig. 1; and Fig. 4 is a vertical crosssection of the machine on a line corresponding to y y, Fig. 1.

The machine thus shown is of a dual character, as already indicated, and constructed to out up or reduce two logs to fiber at the same time with the same set of saws. To this end I provide mechanism for handling both legs together or independently, as may be preferred, and for taking care of the product of the machine through a suitable suction blower or fan, as also will hereinafter appear.

A represents the main frame of the machine, which may be of any suitable build or style and of the requisite firmness and size for the purpose.

B and B represent the wood logs, respectively, and O is the power-shaft, carrying a series of saws 0, arranged between the logs,

so that in operation as the logs are reversely.

rotated the saws will cut downward upon one log and upward upon the other, and provision is made to take care of the fiber from both logs through a suction-blower T, as will appear. The logs themselves are supported from the main frame upon rocking supports D, which are shown here as having differential pivot-spindles d at the power side of the machine, which bear other operating parts of the mechanism, as hereinafter described. The supports D are connected in pairs by cross-bars d, and at the top of the said supports D on one side of the machine there is a short shaft E, rotatable in a tubular bearing (1 on said support and provided with a gear-wheel F on its outer end and with spurs f on the head of said shaft inside, which engage the log and serve to support and rotate the same when the shaft E is rotated. The opposite end of the log is suitably sustained by the outer of said supports D. The mechanism through which this rotation occurs originates with the power shaft 0 and pinion c thereon, meshing with friction gear-wheel G, supported on its own shaft G. Otherwise the said wheel G is a friction-wheel and has a flat side upon which are frictionally engaged a set of rollers 72., one for each ,log, and each supported upon a lengthwisemovable shaft H. The said shafts H are carried in suitable bearings h, fiXed upon the side of the main frame, and are lengthwise adjustable or movable therein, so as to bring the friction-roller h nearer to or farther from the actual center of wheel G, according to the size or thickness of the log B or B. The larger the log the farther the roller from the center of wheel G. The said shaft H is splined and carries two Worms 72, and 72 Power for rotating the log is communicated from worm h 'through gear K, having a hub rigid with the small gear L, which meshes with gear F, sleeved upon shaft E. Through this mechanism a fixed and definitespeed of rotation is imparted to the logs, according to the position of the friction-roller h upon the side of wheel G, and it is possible to have one of said rollers working near the center of the wheel G while the other is near its pefriphery, thus providing for operating upon logs of difierent sizesthat is, one log may be practically reduced or cut away, while the other log may have just been placed in position, and in the further mechanism to be described I provide for this, so that the work may progress as to one log while it is stopped as to the other to replace a log or for any other purpose of convenience.

the saws c.

Now returning to the worm 71. it will be noticed that it is in mesh with an eccentrically-mounted gear N, the shaft of which is rotarily controlled by a hand-lever n, so that when said gear is 'turned in one direction through the lever n it will be thrown out of mesh with pinion 7L3 and when rotated in the opposite direction will be brought into mesh with it. On said shaft 11, above handle '11, is a worm 11 in mesh with segmental rack O and through which two movements are effected, one ofwhich is the feed of the logs to the saws on their pivot-supports and the other is the rate of speed at which the log is rotated by controlling the position of friction-roller h on wheel G. The first line of mechanism proceeding from worm n is by the segmental rack O, which is rigidly secured upon spindle d on log-support D, so that when the said segment is rotated through worm n it likewise rotates, rocks, or tilts the support D on its pivot, and as said support has its pivotbearing in its spindle d and a large circle of rotation from that point for the log it follows that the segment 0 has sufficient length of movement to carry the log from its largest to its smallest working dimensions toward So it follows that as the said support D is swung on its pivot by segment 0 a gradual but definite feed forward of the log is imparted. This of course is wholly ditferent from the rotation of the log through gears K, L, and F. Now returning to the other line of mechanism, it is also observed that the segment 0 meshes with rackbar R, adapted to slide in a suitable bearing 1', rigid with the main frame, Fig. 3, and which has an arm r extending outward at one end and on which is a hub T The shaft H projects through this hub and is rotatable therein, but is confined as to axial movement. So it follows also that when the said rack-bar is caused to travel in either direction of its length the shaft H is carried with it, and the actuations of said shaft and the friction-roller 71. thereon to and from the axial center of wheel G are through this rack-bar and its arm extension and segment-rack 0. Thus both the speed of rotation of either log is governed primarily by the position of frictionroller h in respect to the wheel G, as is also the feed to the saws through support D, and the line of mechanism from friction-roller h to either log can be suddenly stopped by throwing gear N out of mesh with worm 71 as already described. When this is done, the operator can also change the position of roller h in respect to wheel G by drawing out or pushing back the shaft H, upon which roller 71. is splined.

The rollers h are provided in this instance with a counter friction-wheel G which is pressed inward through spring g, and antifriction-bearings supported on the outer extension or extremity of shaft G. In this way the said rollers are kept faithfully to their work, and more or less spring tension can be applied, as may be required for this purpose.

About the saws c and over the point of accumulations of the cut fiber I provide a suitable hood or covering 2, so as to utilize a suction-blower T, fixed upon drive-shaft C, and which has its discharge arranged to convey the product into any suitable storage-room or other place provided for the fiber.

By the foregoing construction a machine of double producing capacity is made with comparatively little more expense than would be required to carry and operate upon a single log, and the unitary character of the machine occurs in its construction, whereby one log is cut on the down travel of the teeth and the other on their up travel, and the power and control are from the same shaft and frictionwheel G, as already described.

What I claim isv 1. In a wood-fiber-cutting machine, a powerdriven shaft and a line of saws thereon and a dual log rotating and feeding mechanism actuated from said shaft and comprising a power-driven wheel and friction-rollers in engagement therewith to drive said mechanism and rotate and feed the logs to the saws, substantially as described.
